Fwd: How to turnoff autovacuum

[mark armon <1994hejian@xxxxxxxxx>]

Just follow the tutorial. In the tutorial I need to set the autovacuum off. 

Here is how I set the autovacuum off. 

1. Locate the postgresql.conf.  
2. edit the postgresql.conf using notepad. As the picture attached. Previously it's on now it's off. 
3. close and save postgresql.conf then open service-msc
4. restart  the postgresql service. 
5. open psql type: show autovacuum; 

But the result is ON. 

So that's my knowledge about  how to set the parameters. But it failed. So please tell me how to set the autovacuum off.
